It is desirable to make the nut 72 slidable in the axial direction by making the shaft diameter smaller than that of the male screw portion 73.

  Further, the nut 72 may be attached to at least the belt loose side with respect to the pulley base portion 61. In order to prevent the nut from loosening, as shown in FIG. The pulley base portion 61 may be sandwiched and fixed at 72. When the nut 72 is attached only to the belt slack side with respect to the pulley base portion 61, it is desirable to take some measures to prevent slack.

  Even with the configuration described above, as in the first and second embodiments, without attaching a spring member for elastically urging the driven pulley 43 toward the belt tension side, the belt 45 can be attached and detached, particularly during assembly. The belt 45 can be easily attached.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the number of pulleys constituting the belt drive mechanism is not limited to two and may be three or more, and a plurality of them may be specified pulleys. The specific pulley is not limited to the driven pulley, and may be a driving pulley driven by driving means.

  In the embodiment, the pulley base portion 61 is guided at two locations by the pulley guide portion 62, and the movement restriction by the pulley position restricting means 47 and 71 to 73 is performed at the two locations, respectively. The pulley base portion 61 may be configured to be guided at one or three or more locations, and may be configured to perform movement regulation by the pulley position regulating means 47, 71 to 73 at those one or three or more locations. .

  It is not necessary to provide a pair of belt driving mechanisms, and the movable body may be operated independently.

  The pulley position restricting means may be any means that restricts the movement of the specific pulley 43 toward the belt loosening side in a state where the belt 45 is stretched, and there are various aspects other than the first to third embodiments. Conceivable. For example, on the pulley guide portion 62, a regulation piece (pulley which can be expanded and contracted in the radial direction and elastically biased in the expansion direction corresponding to the belt loose side with respect to the position of the pulley base portion 61 in a state where the belt 45 is stretched. One or a plurality of position restricting means) may be provided. The restricting piece is formed, for example, in a substantially triangular shape so that the protruding width gradually increases from the belt slack side toward the belt tension side, and when the pulley base 61 is moved to the belt tension side, the pulley base is formed. When the belt 61 is pushed inward by the portion 61 to allow the passage thereof, conversely, when the belt 61 is moved toward the belt slack side, the passage of the pulley base portion 61 may be prevented unless the belt is contracted inward.

  Even with this configuration, as in the first to third embodiments, the belt 45 can be attached and detached, particularly during assembly, without attaching a spring member for elastically biasing the driven pulley 43 toward the belt tension side. The belt 45 can be easily attached.

  Further, the present invention can be similarly implemented not only in a ball game machine other than a pachinko machine, but also in various game machines other than a ball game machine such as a slot machine.
